I was at the post office today. I tried to send stuff and pay with my credit card. They refused to accept my credit card because instead of my signature on the back, I have "ASK FOR ID." You see... because they can't verify who I am without my signature on the back of the card....

... accept, of course, for the fact that I've requested they check my ID, which is my state issued Driver's License with my name, picture and signature... on it.
